Which of the following is true about the expression sqrt3*sqrt2

Mars2501 [29]

Answer:

<h2>Option B is the right answer.</h2>

Step-by-step explanation:

$\sqrt{3} , \sqrt{2}$ are two irrational numbers, that is, they can not be shown as the fraction of two integers.

$\sqrt{3} \times\sqrt{2} = \sqrt{6}$

$\sqrt{6}$ is also a irrational number, since it also can not be represented as the fraction of integers.

Hence, the given expression represent the product of two irrational number and is equivalent to an irrational number.

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find

Wewaii [24]

Answer:

$y=120,000(1.055)^x$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the value of the home

x is the number of years

a is the initial value

r is the rate of change

we have

$a=\$120,000\\r=5.5\%=5.5/100=0.055$

substitute

$y=120,000(1+0.055)^x$

$y=120,000(1.055)^x$
